Rigging complex mechanical shapes
A rigging method without physics


To simplify this report, consider only two-dimensional space.
It is also assumed that the lower lever has a smooth convex curve and the upper lever is a straight line on the side where the two levers touch. With this assumption, rigging with Armature was able to solve the problem.

First, for simplicity, coincides the coordinate system of the lower lever object with the Armature space. In other words, only the upper lever slides on the fixed lower lever in the Armature space. This behavior could be realized by using Follow Path and IK constraints. Then, the behavior of bones was transferred to the both lever objects. Finally, the rotating shaft of the upper lever was fixed by using a Copy Rotation constraint.
